signal(s) connected to
connector STO is broken
during start or run.
Power unit memory has
cleared.
The hardware of the drive does
not match the information
stored in the memory. This
may occur e.g. after a firmware
update.
Problem with internal
temperature measurement of
the drive.
Safe motor temperature fault is
generated and STO
event/fault/warning is not
generated.
Note: If only one STO channel
is opened, fault 5090 STO
hardware failure
Communication failure to
standard I/O.
Cooling fan stuck or
disconnected.
Connection between the drive
control unit and the power unit
is lost.
Measurement circuit fault.
Power unit power supply
failure.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
Charging feedback signal
missing.
The power unit logic has
generated a fault which is not
known by the software.
Firmware and FPGA versions
are incompatible.

What to do
Check safety circuit connections. For
more information, see chapter The Safe
torque off function in the Hardware
manual of the drive and description of
